Lack of immunity in Ayurveda is considered as a life style disorder. The method is to consider diet, daily activities and medication when treating lack of immunity. Good diet with healthy daily activities with no medication will not serve the purpose. Similarly, healthy daily activities and medication with no control over the diet also spoils the regimen. Similarly, good diet with medication and unhealthy daily activities will not support the plan. All the three points should go hand in hand for a better and long-lasting immunity.
